PHILADELPHIA — The 76ers have yet to endure any roster cuts by first-year coach Brett Brown, which means all 20 players featured on their training-camp roster boarded a Spain-bound flight Thursday morning as the team prepared to kick off the European leg of its preseason this weekend.

They’ll do (a little) sightseeing, (plenty of) practicing and (on two occasions) game-playing — beginning with Sunday’s date against the local club in Spain, Bilbao Basket. The Sixers wrap up their overseas jaunt Tuesday in Manchester, England, against fellow NBA club Oklahoma City.

“In a twisted way, to get this group together and go do something like that with them, I think that trumps the disruption of two-a-days or you miss a day and a half,” said Brown, the first-year coach. “I’m excited to take these guys overseas to play a FIBA game and go to Manchester and play an NBA game.”

It’s too soon for Brown to suggest what he has, or doesn’t have, in front of him. So the Sixers spent the week in an excitable state about the prospect of leaving the States.

“You know, chemistry is not just something you develop on the court. It’s hanging out off of it as well,” said center Spencer Hawes, a European traveler this summer who expected his tender left knee to be cleared medically so he can participate in both exhibitions. “Being over there in a different setting will be beneficial in that regard.”

Thad Young echoed some of Hawes’ sentiment.

“It won’t be us going out of town and going to the clubs and all that,” he said. “We’ll have a great time and a great experience.”

Two points of note from the Sixers’ preseason trip emanate from their travel roster.

Forward Royce White, the Houston Rockets’ first-round draft pick in 2012, who missed all of last season with anxiety issues and a fear of flying, was expected to come along for the trip. Similarly, injured center Nerlens Noel, who won’t figure into the Sixers’ rotation until possibly January, was joining his teammates for a little bonding.

And then there are guys like rookie Khalif Wyatt, who’s just looking forward to having his passport stamped.

“I’ve never been out of the country,” the Temple product said, “so it’ll be a good experience.”

Added White: “Any time you get a chance to do anything as a team where you spend time away from the court together is a good opportunity.”
